Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0026] Please see Figure 1-7 This invention provides a technical solution: an overhead line breakage protection device, including a base plate 5 mounted on an angle iron 3, a breakage protection mechanism mounted on the base plate 5, the breakage protection mechanism including a protection box 6, a partition 7 disposed within the cavity of the protection box 6, a blade 8, and a drive assembly for driving the blade 8 to slide and cut the wire 4; the protection box 6 is slidably mounted on the base plate 5, the base plate 5 is provided with a pre-tightening member to increase the sliding resistance of the protection box 6, the partition 7 is uniformly provided with multiple sets of blade grooves 9 along its circumference, the blade 8 is provided with multiple sets corresponding to the blade grooves 9 and is slidably mounted within the blade grooves 9 along the radial direction of the partition 7, a sliding rod 10 is provided on one end face of the blade 8, the sliding rod 10 extends to the outside of the partition 7, a positioning slider 11 is provided on the outer circumference of the sliding rod 10, and the partition 7 is provided with rod grooves 12 for sliding the sliding rod 10 and for sliding the positioning slider 11. The positioning groove 13 is movable, and the sliding of the positioning slider 11 in the positioning groove 13 allows the blade 8 to slide stably in the blade groove 9 along the radial direction of the partition 7. After multiple blades 8 slide and come into contact, they will form a complete circle. The inner cavity of the protective box 6 is provided with a toothed disc 14. One end of the slide rod 10 located outside the partition 7 passes through the toothed disc 14, and the end passing through the toothed disc 14 is provided with a limiting plate 15 for engaging with the toothed disc 14. The toothed disc 14 is provided with an arc-shaped groove 16 for the slide rod 10 to slide. The arc-shaped groove 16 gradually moves away from the axis of the toothed disc 14 from one end to the other. The wire breakage protection mechanism also includes a wire hole 17 that passes through the protective box 6, the partition 7, and the toothed disc 14. The protective box 6 is provided with a fixing part for fixing the wire 4 at the wire hole 17. It should be noted that the inner wall of the wire hole 17 can be provided with an insulating layer to protect the wire 4.

[0027] Specifically, a drive box 18 is provided on one side of the protective box 6. The drive assembly includes a drive motor 19 fixed in the inner cavity of the drive box 18 and a drive gear 20 that meshes with the gear plate 14. The output end of the drive motor 19 is fixedly connected to the shaft of the drive gear 20.

[0028] Specifically, the top of the substrate 5 is provided with a groove 21, and the bottom of the protective box 6 is provided with a sliding block 22. The sliding block 22 is slidably disposed in the groove 21. The two ends of the substrate 5 located in the groove 21 are fixed with guide rods 23. The guide rods 23 pass through the sliding block 22. The sliding block 22 can slide stably in the groove 21 by cooperating with the guide rods 23.

[0029] Specifically, the pretensioning component includes a spring 24. There are two sets of springs 24, which are respectively set on both sides of the sliding block 22. The springs 24 are sleeved on the guide rod 23. In the initial state, the springs 24 on both sides make the sliding block 22 located in the middle position of the slide groove 21. The springs 24 can be of different thicknesses according to the actual use environment, so as to control how much tension the protective box 6 needs to be subjected to before it slides.

[0030] Specifically, a battery box 25 is provided on one side of the protection box 6. The battery box 25 contains a battery 26 that supplies power to the drive motor 19. The positive terminal of the battery 26 is connected to a positive terminal 27 via a wire 4, and the negative terminal of the battery 26 is connected to a negative terminal 28 via a wire 4. A base rod 29 is provided inside the battery box 25. The base rod 29 contains a mating groove 30 for sliding the positive terminal 27 and the negative terminal 28. A push rod 32 is provided on the base rod 29 to push the positive terminal 27 and the negative terminal 28 into contact after sliding. When a pole 1 tilts, it will pull the protection box 6 to slide in the sliding groove 21, thereby causing the push rod 32 to push the positive terminal 27 or the negative terminal 28 to move.

[0031] Specifically, the top of the substrate 5 is provided with fixing plates 31 at the front and rear ends of the slide groove 21, and the ends of the push rods 32 on both sides are fixed to the fixing plates 31 on both sides respectively, and the wire hole 17 passes through the fixing plates 31 on both sides.

[0032] Specifically, the positive terminal 27 and the negative terminal 28 are provided with a rubber layer 33 on their sidewalls. The rubber layer 33 is in contact with the inner wall of the mating groove 30. The rubber layer 33 will increase the friction force of the positive terminal 27 and the negative terminal 28 sliding in the mating groove 30. When the push rod 32 does not push the positive terminal 27 or the negative terminal 28, the positive terminal 27 and the negative terminal 28 will not move.

[0033] Specifically, the fasteners include bolts 34 threaded to the wire holes 17 on both sides of the protective box 6. A rubber pressure plate 35 is rotatably provided at one end of the bolt 34 near the wire hole 17. The bottom end of the rubber pressure plate 35 is provided with an arc-shaped groove. By rotating the bolt 34, the rubber pressure plate 35 can be driven to press the wire 4 downward, thereby fixing the protective box 6 and the wire 4. When the wire 4 is pulled, it will cause the protective box 6 to slide on the base plate 5.

[0034] A specific application example of this embodiment is as follows:

[0035] When this device is in use, the wire 4 is installed through the fixing plate 31, the protective box 6, the partition plate 7 inside the protective box 6, and the wire hole 17 on the gear plate 14. By rotating the bolts 34 at both ends of the protective box 6, the rubber pressure plate 35 is moved down to press and fix the wire 4. When a pole 1 is tilted due to environmental factors or a wire 4 is struck by an external force, the protective box 6 will slide to one side on the base plate 5. The sliding of the protective box 6 will cause the push rod 32 to slide in the docking groove 30, pushing the positive terminal 27 or the negative terminal 28. When the pulling force of the wire 4 is too large and the protective box 6 slides a large distance, the push rod 32 will push the negative terminal 28 to contact the positive terminal 27, thereby forming a closed loop in the circuit between the battery 26 and the drive motor 19, thus starting the drive motor 19. The start of the drive motor 19 will drive the drive gear 20 to rotate. The rotation of the drive gear 20 will drive the slide rod 10 to slide in the arc groove 16 and simultaneously in the rod groove 12. The sliding of the slide rod 10 will drive the blade plate 8 to slide radially along the wire hole 17. After multiple blade plates 8 contact, they will form a complete circle and cut the wire 4, preventing the wire 4 from being pulled down by excessive pulling force, thus preventing the row of poles 1 from tilting.
